Definitions
- the present invention regards a cartridge for refilling of methanol or methanol/water as fuel to an electronic unit with a fuel cell that is using the fiiel for production of electric power for operation of the electronic unit.
- the cartridge is leakage proof, tamper proof and child proof.
- the invention also regards said electronic unit and a fuel container for an electronic unit.
- the cartridge, the electronic unit and the fuel container are equipped with a connection device that makes the units leakage proof, non- tempering and child proof with respect to the fuel.
- Fuel cells are at present an alternative for delivery of electric power to electronic units and other means that require electric power for operation.
- a number of fuel cells exist for example "Polymer Exchange Membrane” (PEM) fuel cells based on hydrogen as fuel, and “Direct Methanol Fuel Cells” (DMFC) based on methanol as fuel.
- PEM Polymer Exchange Membrane
- DMFC Direct Methanol Fuel Cells
- Methanol is a preferable fuel for fuel cells due to its high concentration of hydrogen, it can be reformed at low temperatures, it is liquid at ambient conditions, it is easily biological degradable and it can be produced from fossil materials and biomaterials. Even though methanol has many preferable properties it is both flammable and toxic for humans and other organisms. If methanol is to be commonly used as fuel in the consumer market, the utilization has to entail sufficient safety against unwanted exposure and leakage of the fuel.
- a cartridge for refilling of methanol or methanol/water as fuel to an electronic unit with a fuel cell, which cartridge is constructed and distinguished as apparent from claim 1.
- An electronic unit is also provided, with construction and distinguishing features as apparent from claim 5.
- a fuel container is provided, with construction and distinguishing features as apparent from claim 10.
- a first sealing means it is considered any sealing means that can provide the aimed function, for example a plate, a sphere cap, a sphere segment, a sphere, a cone or another means that can be sealingly arranged against the inner cartridge wall.
- a plate is most preferred because of simplicity.
- a second sealing means it is considered any sealing means that can provide the aimed function, for example a cone, a sphere cap, a sphere segment, a sphere, a plate or another means that can be sealingly arranged against the outer cartridge wall.
- an oppositely oriented cone is most preferred because of the preferable properties with respect to protection against tampering, fuel drainage and aligning.
- cylinder it is considered any elongated body that can be moved an axial distance in through an opening in the inner cartridge wall, such that in an inner position the cylinder's passage way for fuel is open, while in an outer position the cylinder's passage way for fuel is closed.
- the passage way can be a boring outside on the cylinder, or the cylinder can be hollow in form of a pipe that is closed in its upper end and preferably also in its lower end, with openings in the pipe wall for fuel.
- the passage way in the cylinder is thereby considered as openings for fluid communication.
- a hollow cylinder is preferred because of simplicity for manufacture.
- the connection device is preferably arranged within the cartridge, and encompassed by the outer cartridge wall, a distance from the opening, for increased safety against tampering.
- a similar construction applies for the fuel container.
- units that are to be connected are equipped with adapted dimensions such that the outer walls and outer pipes in the connection devices can be passed into each other, preferably by screwing.
- an adapted protective cap is screwed on to the connection device, such that three barriers exist against leakage.
- Figure 1 illustrates a section of the cartridge for filling of methanol or other fuel, which section illustrates the connection device in form of an outlet device according to the present invention.
- Figure 2 illustrates the cartridge illustrated on Figure 1 and its outlet device, and a connection device in form of an inlet device to a fuel container for example into an electronic unit.
- Figure 3 illustrates the connection of the connecting devices according to the present invention.
- FIG. 1 a cartridge 1 according to the invention, containing methanol, is illustrated. More specific, an inner cartridge wall 2 is illustrated, through which a hole is arranged and a hollow cylinder 4 is brought through with a plate 3 on the upper end of the cylinder.
- a spring 8 is arranged, and the hollow cylinder is equipped with at least two holes or set of holes 5 at different distance from the upper end of the cylinder. With the cylinder in an outer position the holes 5 are outside the inner cartridge wall.
- an oppositely oriented cone 6 is arranged, sealingly pressed against an oppositely oriented cone form constituting a part of an outer cartridge wall 7.
- a hole is provided, and below said hole a pipe or a flow way is arranged such that the hole lays within the end of the pipe or the flow way.
- a push bar 10 is arranged downwards from the apex of the cone.
- the spring 8 is pressing such that the plate 3 is sealingly pressed against the inner cartridge wall 2.
- the spring is pressing the cone 6 sealingly against the cone form 7.
- sealing material is preferably arranged, such as fuel compatible elastomeric material, which is illustrated on the figures in form of the most densely hatched material.
- the fuel in the cartridge 1 is enclosed by two sealing barriers, namely between the plate 3 and the inner cartridge wall 2 and between the cone 6 and the cone form 7 that constitutes a part of the outer cartridge wall.
- the hollow cylinder 4 is axially slidable. If a further push bar is brought up through the pipe from below towards the apex of the cone 6, it will hit the push bar 10 and push it, the cone, the cylinder and the plate axially towards the center of the cartridge. If the displacement is sufficient the upper set of holes or the upper hole in the hollow cylinder 4 will be displaced such that said holes become openings through which fuel can flow into the hollow cylinder 4 from the interior of the cartridge.
- FIG. 2 illustrates the cartridge, the outlet device and a corresponding inlet device on the unit where the cartridge is to be connected.
- the unit is an electronic unit with a fuel tank for storage of fuel for utilization in a fuel cell for production of electric power for operation of the electronic unit.
- the outlet device and the inlet device are in principle identical, but as mentioned above and as illustrated on the figure an additional push bar is required.
- the push bar or the push bars can be arranged on either the outlet device, the inlet device or both, in that the combined length of push bar is adapted such that the flow through each unit becomes as described above. More specific it is meant that when the connections are mated, for example by screwing, the displacement of the hollow cylinders with holes, sealing surfaces and cones, is such that the one set of holes on each cylinder comes into the respective fuel container, while the other set of holes are outside, such that fluid can communicate from one tank to the next, i.e. from the cartridge to a fuel tank in the electronic unit. Connection and flow of fuel is further illustrated on Figure 3. Methanol flows from the cartridge to the fuel tank while air flows the opposite way. The methanol flow is illustrated with arrows.
- connection devices are identical, except from the push bar and the outer walls and pipes/flow ways that are to be mated, as described above.
- a push bar is arranged from the lower end of the cylinder, through openings in the outer cartridge wall and a distance into a pipe below, in that the length of the push bar is adapted such that by mating the connection a correspondingly constructed push bar on the connection device of the connected unit will together with the first mentioned push bar provide a sufficient displacement in the connection devices so that fuel can be passed from the cartridge to a fuel container connected to the connection device of the second unit. So is a standardized embodiment of the push bars achieved.
- the cartridge and the fuel container is preferably equipped with a protective cap on the connection devices.
- the connection devices per se are preferably built into a protective cap that for example can include threads for connection, for example male threads on one connection and female threads on the corresponding connection.
- All containers, which means the cartridge and the fuel containers in the electronic unit are preferably equipped with double walls and are manufactured by non-sparking, recyclable materials, such as stainless steel.
- the electronic unit is chosen amongst a mobile telephone, a computer, a calculation unit, a camera, a recording unit and any other electric power operated electronic unit.
- the fuel containers are either integrated into the electronic unit, such that refilling is from the cartridge according to the invention, or it is put into the electronic unit.
